Hide file tab is used to remove the file tab from view on the /admin/content section.

The motivation for this is due to the confusion between the File tab and Media tab (when enabled). This could be solved with the use of the 'Access the Files overview page' permission however it cannot be removed for the admin role.

Note: this will only hide the tab and does not restrict access to it for users that actually have the 'Access the Files overview page' permission.
